In a recent theoretical work by Narimanov and Kildishev (2009 Appl. Phys. Lett. 95 041106) an optical omnidirectional light absorber based on metamaterials was proposed, in which theoretical analysis and numerical simulations showed that all optical waves hitting the absorber are trapped and absorbed. Here we report the first experimental demonstration of an omnidirectional electromagnetic absorber in the microwave frequency. The proposed device is composed of non-resonant and resonant… Expand

A simple metasurface microwave absorber is proposed that has one metal-backed logarithmic spiral resonator as the unit cell and can absorb >95% of normally incident microwave energy within the frequency range of 6  GHz–37 GHz as a result of the scale invariant geometry and the Fabry-Perot-type resonances of the resonator.

Electromagnetic field attractor made of gradient index metamaterials.
